How opening this case works
One spin of the Bio case costs 545.82 coins and draws a single item from the 12 listed above. You can open one at a time or up to four at once; four spins cost four times the price and are four independent draws, not one improved one.
Whatever drops is credited to your balance at its full value in coins. You can spend that on the marketplace, stake it in any other mode, or buy the item itself and withdraw it to your Steam inventory.
The Demo button spins this exact drop table without spending anything, so you can see how the case behaves before committing coins to it.
Odds and fairness
The winning ticket is drawn from Random.org before the animation plays, and every finished spin carries a Verify button that opens the record behind it. Random.org stamps each request with a serial number that only ever increases, so a quietly re-drawn result would leave a gap in the published sequence.
This case is rated medium volatility. That describes how swingy its payouts are relative to its price, not how generous it is: it blends how often a spin returns less than half the 545.82 coin price with how large the top drop is against it.
